If only one row was inserted and Oid is the numeric OID of the inserted row. The following table shows the output messages and their meaning: Output message

If the column allows NULL values, we can ignore a column from the PostgreSQL insert command.

We must offer each NOT NULL column value if we are inserting the records into a table using the PostgreSQL insert command.

If DEFAULT is specified, the consistent column will be occupied with its default value. If expression1 is specified, then column1 would be granted the value of expression1, column2 would be given the value of expression2, and so on. These are the values allocated to the columns in the table. And it is used in the third syntax.Įxpression1 | DEFAULT, expression2 | DEFAULT It is used when we want to insert the data from another table.

An INSERT without a column list requires you to provide a value for very column. Message returned if only one row was inserted. You can INSERT single or multiple rows at a time. The following table summarizes the output messages and their meaning − INSERT INTO TABLE_NAME VALUES (value1,value2,value3.valueN) The SQL INSERT INTO syntax would be as follows − However, make sure the order of the values is in the same order as the columns in the table.

You may not need to specify the column(s) name in the SQL query if you are adding values for all the columns of the table. The values supplied by the VALUES clause or query are associated with the explicit or implicit column list left-to-right. The target column names can be listed in any order. Here, column1, lumnN are the names of the columns in the table into which you want to insert data.
